For those of you who like to save money...
TCU for about $300, no core fee.
My final costs for the blue-tooth upgrade:
$230 TCU (e-bay)
$135 FZD (e-bay)
$100 all other parts (Tischer)
-----
$465
My buddy is programming it for me (hopefully), for $30...so all in all, about $500 complete on the "somewhat" cheap. If not, I saw on the OEM alarm thread, that they can only charge you an hour & a half labor for the install of it (the alarm), and that included programming (about $150 total). I also purchased an OEM alarm, so if my buddy can't do it, that will be plan B (need to find out if the dealer alarm programming will take care of both).
On the e-bay parts, I found the exact part numbers Evan (Tischer) had sent me, and both the TCU and FZD happened to be people who were taking "Or Best Offer." I tried $200 on the TCU (he was asking $299) and 229 was the best I did...on the FZD the guy took my first offer (he was asking $189).
Hope this info can help some of you get some good bang for your buck. I wish you all luck and patience.
